The film, starring Tilda Swinton, Jake Gyllenhaal and Paul Dano, began prinicipal photography on April 22.

Steven Yeun, one of the stars of The Walking Dead, has joined the cast of Okja, the latest movie from Snowpiercer filmmaker Bong Joon-Ho.

Plan B is producing the project, which will be released by Netflix. It kicked off production on April 22, and will shoot in South Korea, Canada and the U.S., in English and Korean.

Tilda Swinton, Jake Gyllenhaal and Paul Dano are already set for the unique monster project. Along with Yuen, Devon Bostick (The 100), Lily Collins (To The Bone), Byun Heebong (The Host), Shirley Henderson (Anna Karenina), Daniel Henshall (The Babadook), Yoon Je Moon (Mother) and Choi Wooshik (Set Me Free) have joined the cast.

The story centers on a girl (Seohyun An) who befriends a genetically manufactured pig named Okja. When the pig grows up to gigantic proportions, the corporation that created him takes him, thrusting the girl, now a teen, into a mission to take it back.

Swinton is playing the head of the corporation (and her twin sister!) while Gyllenhaal is a zoologist.  Dano is an animal activist looking to expose the corporation’s dastardly dealings.

Yeun is one of the last remaining series regulars from the pilot of the AMC zombie drama, although his character's fate was left in question at the end of season six. Season seven premieres in October.

Since breaking out on Walking Dead, Yuen has largely stuck to making a few handful appearances on the small-screen and doing some voicework, although he did star in the 2014 indie sci-fi movie I Origins.

Yuen is repped by Paradigm.
